Most Helpful Customer Reviews

I've used the battery fairly regularly and haven't had a single hitch with it. I'm taking them at their word that they had a bad batch but left 1 star off given the circumstances.

Product is great, customer service was insistent on getting their star rating back up.

EDIT 04/28/2014

The seller claims that there was a bad [early] shipment and has sent me a replacement to inspect. I plan to give the battery a second, albeit a cautious, chance. I'll update this review as soon as I've used it for awhile.

BUYER WARNING: This cable burned on the first charge. I've uploaded images of the battery with the cable still plugged in.

The Mpow Ultra-Slim 8000mAh Power Bank External Battery is a compact and useful little gadget that is solidly built with a very clean aluminum design. All the while, this sleek, 8 ounce battery (6" x 2 3/4" x 3/8") will fit into your side pocket or bag effortlessly. The separate LED indicator lights also provides a more precise telling of the remaining battery power of the unit itself, which fades seamlessly beneath the surface of the battery pack when the unit is in an off state. All available ports are placed on one end of the device, which includes a 5V/1A micro-USB input, as well as a 5V/2A (max) standard USB output charge port that is compatible with an assortment of USB-chargeable electronics.

When testing the Mpow on its functionality, I connected my iPhone 5S (as well as an assortment of other devices later on) to the battery device with the appropriate charge cable. To activate the battery and let the charging begin, I simply had to press the single power button on the unit. Simple.

Charging my phone from 10% to full took roughly an hour or so. I was able to get two and a half charges for my phone from a fully charged battery pack. This is with the phone on, connected, and with apps running in the background.

A standard micro-USB was also provided for those who have Android or other compatible devices. No Apple charge cable or adapters were provided, but the original Lightning cable that came with my phone worked just fine.Read more ›

I'VE ONLY USED THIS A FEW TIMES SINCE I'VE PURCHASED IT BACK IN MAY 2014....ALL THAT TIME I'VE ONLY RE-CHARGED IT ONCE. TODAY IS OCT 2014 AND WHEN I WENT TO PLUG THE USB CHARGER INTO THE UNIT, THE CHEAP THING BROKE ON ME!!!! IT SANK IN AND NOW THERE'S A RATTLING SOUND AND THE USB PORT WON'T PROPERLY PLUG UP TO THE USB CORD!!! I EXPECTED BETTER CRAFTSMANSHIP FROM THIS PRODUCT...IT'S HEAVY IN WEIGHT SO I THOUGHT IT WAS SOLID, BUT THEN THE PLUG PORTS SHOULD BE SOLID ALSO, AND NOT SO FRAGILE LIKE A CHEAP BATTERY! NOW I HAVE TO LOG ON AND BUY ANOTHER ONE!

Totally worth it with what I paid for. Now, I put away my car charger and I only need the backup battery pack in my car. I will be able to open multiple applications on my way. And I don't have to charge the Mpow battery for very often. I only charge it for every other day or three times per week. Thanks a lot!

I would like to change my rating from 5 stars to 3 because it suddenly stopped working what it been doing like last month. My phone didn't get charge anymore and it only charged less than 1 min and then stopped. I kept on doing plug in and unplug and still didn't work. I thought something to do with my battery and the USB cable. I have troubleshot with my battery and USB cable with wall plug and car charger and it perfectly worked. So something went wrong with the Mpow device clearly. I was pretty upset because it only last for one and half month. I wanted to return if I can. I wouldn't recommend to purchase this device anymore.

It arrived DOA, the charger would not charge and kept giving me problems so I returned it to Amazon.. I guess just be careful of authenticity. Mine wasn't metal, it was like plastic.

The Seller reached out to me, sent me a new one that now works great, no issues whatsoever. I have been using it for roughly 3 days and the charge holds, surprisingly charged my iPhone almost 3 times over in the whole day and still had charge. Awesome.. would definitely recommend them! Also, works with my iPad too!

I use this battery pack infrequently, so this failure happened just recently after the return period expired. The USB ports suddenly came loose, so they move in when you try to plug in. Almost can't be plugged in. I can feel that the ports are going come totally loose soon and can't be plugged in anymore ...

Edit - Seller is very easy to work with. Great customer service. My unit was a lemon, and seller took care of me.

I have several Power Banks like this that I use regularly, so I was willing to accept another for review from Mpow. I've reviewed several other items from Mpow as well, and everything I've gotten has been top notch quality. This power bank is no different. It took about 3 hours to load it with it's initial charge using my computer USB port, and I waited until the next day to use it to recharge my phone (which I always seem to let run down :( ). When I went to use it the next day, it hadn't lost any of its charge, and was able to fully charge my LG G2 phone from about 12% to 98% in less than 2 hours. The power bank indicated that it still had more than half of it's capacity of charge remaining. I always have my Nexus 7 Tablet with me, and it too often suffers from my charging neglect, So I plugged that tablet into this charger during class (summer classes are over 2 hours), and by the end of class it had gone from 17% to 64%. It was a slower charge, but that tablet always charges slower than my phone does.

I don't know any of the technical things about this charger other than it has a much higher capacity than many I've seen on Amazon, or elsewhere. I don't think it is that much faster than any of the others I've tried, but knowing it has more juice to start, makes it a power bank I want to have around. I've used it daily now for about a week and a half without any issues, so would highly recommend it.

I received a complimentary sample of this power bank in exchange for an honest and unbiased review.
